Gowanda’s 21M332M Molded Unshielded RF Coils are a testament to their leadership in high-quality electronic components. These coils, weighing 1.7 grams, feature dimensions of 14.224 × 5.588 × 5.588 mm and belong to the 21M series. Designed for through-hole technology (THT) mounting, they cater to commercial off-the-shelf (COTS) applications. With an inductance of 33 µH and a minimum Q factor of 60, they operate at a test frequency of 2.5 MHz. The coils have a DC resistance of 1.5 Ω and a self-resonant frequency of 20 MHz, supporting a current rating of 0.258 A DC. They are capable of withstanding dielectric withstanding voltages (DWV) of 1000 and 200, with a tolerance of ±20%. The termination type is lead-based with a Sn63Pb37 finish, and the core is made of powdered iron. These coils are not shielded and function within an operating temperature range of -55°C to +105°C. They have a moisture sensitivity level (MSL) of 1 and are packaged in tape and reel (T&R) format. Additionally, they are fungal inert, ensuring reliability in various environments.
